Construction and use of a photomultiplier-tube direct-reading polychromator for emission spectroscopy is described for application to measurement of spectral line intensities from plumes generated by a ruby laser microprobe. Simultaneous correction for background adjacent to each spectral line measured is provided. Advantages include capability of external precision alignment and the use of optically and electronically matched components for recording the line and background intensities. Although the unit is adaptable to commercial spectrographs, the polychromator constructed was made to fit a Czerny-Turner, <i>f</i>/6.3, emission spectrograph (Jarrell-Ash Co., Waltham, Mass.) which had been designed for photographic recording.
